Help! Symptoms disappearing...should i be worried??

Jennifer
From 4.5 weeks up until 5.5 weeks, i had strong symptoms every day. Tons of bloating, completely exhausted 24/7, lots of occasional nausea, really sore boobs, and mild cramping. Last night i noticed i was feeling much better. Woke up today and other than slightly sore boobs and a littlw bloating, im not having any of the other symptoms. I should be enjoying this, but instead im worried that something is wrong! Has anyone experienced sudden loss of sysmptoms and it not been due to miscarrying? I am a bit paranoid because my only other pregnancy did result in miscarriage and even though the baby grew until about 9 weeks, i only had very mild symptoms. Please let me know if im worrying for nothing here!
